In this study,Cu、Zn、Pb、Cr、Ni、Cd and As were analyzed in the soil samples and they were collected on the highways from the west entrance to the top of the south of Wutai Mountain in different elevations and different soil layers.Two indices—the Index of Geoaccumulation and the Potential Ecological Risk Index were used to evaluate the degree of pollution by heavy metals.The results indicated that the soils in study area were characterized by on-to-partial moderate pollution and posed a high potential ecological risk.With the altitude increasing,the degree pollution and the potential ecological risk increased.The degree pollution and the potential ecological risk in the 0-10 cm layer werehigher than that in 10-20 cm layer.The potential ecological risk was characterized by the order of CdAsCuNiCrPbZn with the increase of altitude,which belonged to the level of"high ecological risk"on the whole.The potential comprehensive ecological risk level of 0-10 cm and 10-20 cm soil layers is"the highest ecological risk"and"higher ecological risk"respectively with the predominant risk factor being Cd.
